How to adjust the User Account Control (UAC) settings

IMPORTANT:It is recommended that the User Account Control (UAC) setting not be lowered if at all possible. Lowering the UAC setting can reduce the computer security level and make it more susceptible to security exploits. If the UAC setting does need to be lowered for some reason, be sure to return the UAC setting back to at least the default level as soon as possible.

NOTE: By default, the operating system is configured with the User Account Control (UAC) level set to the second highest setting possible.
